Duet board voltage supply to steppers

Hi All,

So I'm looking into setting up a stepper motor controller circuit, and I just wanted to compare the voltage that my reprap fisher 3D printer uses for the axises, to use as a starting point.
I've got a copy of the schematics, and it suggests that the DC voltage from the mains is what is used - mine is rated at 19v @ ~3A.
The stepper that it uses is rated for 3.3V, does this mean that the motor is being over cooked? Or is it happy to run at this voltage (and maybe higher?).


Regards,
Thomas

The stepper driver will take care of the higher voltage. They run in current control mode anyway. The steppers will be able to run faster then, without loosing torque.
